Advances in machine milking: The influence of milking on teat condition and mastitis risk
A simple method developed and validated by Dr. Pamela Ruegg (Schreiner and Ruegg, 2003) for scoring udder hygiene has proved an invaluable tool to monitor the effect of the cow environment on udder cleanliness. Udder hygiene scores showed a significant association between poor udder hygiene and increasing individual cow linear score and the prevalence of intramammary infection with an environme...
متن کاملElectron microscopic observations on the luminal surface of teat cup liners of milking machines used under South African conditions.
An investigation undertaken with the aid of scanning electron microscopy (SEM) on new and used teat cup liners revealed the generally poor quality of luminal surfaces. Even those of the brand-new distributor controls showed significant faults in the evenness and continuity of the liner surface. A hundred and 500 milkings apparently tend to aggravate faults like cracks, pores, grooves and pits, ...
متن کاملLiners and Teat End Health
In the dairy industry world wide, several hundred types of liners are used to milk dairy cows. The enormous amount of liner types with different characteristics in size, form, consistency and other design and manufacturing characteristics indicate that no ‘best’ liner has been identified in the last 60 or so years since machine milking has become the common method for milk harvesting. Mechanica...
متن کاملEffect of machine milking on bovine teat sinus injury and teat canal keratin
Introduction In Ireland, cows are generally milked with milking machines with 3.2kg clusters, with wide-bore tapered liners (31.6mm – 20.6mm) and 4x0 pulsation (WB). Outside of Ireland, most milking machines have 1.65kg clusters, narrow-bore liners (25.0mm – 20.0mm) and 2x2 pulsation (NB). O’Callaghan (2001) showed that the mouthpiece cavity vacuum was higher with wide-bore tapered liners than ...
متن کاملLatest Thoughts on Methods for Assessing Teat Condition
The Teat Club International (TCI) is an excellent example of an interdisciplinary and international cooperative effort and illustrates the synergies that such collaboration can produce. The group of experts cited in the references to this paper (lead by Graeme Mein, then Eric Hillerton and now Ian Ohnstad) began a dialogue intended to develop a commonly accepted methodology for assessing teat c...
